In both bladder and prostate samples from human and mouse, TMPRSS2 is robustly expressed in various epithelial populations (Figure 2—figure supplement 15A–H). The coronavirus entry receptors are only minimally detected across all bladder cell populations (Figure 2—figure supplement 15A–F), whereas DPP4 and ANPEP are detected in subsets of human prostate luminal cells (~8% of 18%, respectively) (Figure 2—figure supplement 15H). ACE2 expression is low across all recovered populations from the prostate (Figure 2—figure supplement 15H).
